“…9 Limited early postural complexity has been associated with atypical or delayed development. 16,17 Infants diagnosed with or at risk for cerebral palsy demonstrated more repetitive (less complex) postural sway strategies in the early stages of sitting. 16 Infants born preterm used more repetitive postural sway patterns at an adjusted age (AA; ie, chronological age minus weeks preterm) of 1 to 3 weeks and demonstrated less adaptive postural control strategies while learning to control their head in the midline position and during a reaching task.…”

“…16 Infants born preterm used more repetitive postural sway patterns at an adjusted age (AA; ie, chronological age minus weeks preterm) of 1 to 3 weeks and demonstrated less adaptive postural control strategies while learning to control their head in the midline position and during a reaching task. 17,18 Evidence on the role of postural complexity in optimal health, early development, and developmental disabilities suggests that alterations in postural complexity may be predictors of disability. 16,19 A better understanding of the role of postural complexity in the prediction of disability may support the identification of clinically useful tools for predicting motor disability.…”

“…For instance, the center of pressure which can be measured when the infant is sitting or moving in supine position [24], [25] can be considered as a signal that can capture some aspect of movement variation of the whole body. Similarly, Adde et al [26] calculated one 'centroid of motion' time-series from video recordings which is supposed to represent the distribution of motility regarding the four limbs.…”

Movement variation constitutes a crucial feature of infant motor development. Reduced variation of spontaneous infant movements, i.e. stereotyped movements, may indicate severe neurological de cit at an early stage. Hitherto evaluation of movement variation has been mainly restricted to subjective assessment based on observation. is article introduces a method for quantitative assessment yielding an objective de nition of stereotyped movements which may be used for the prognosis of neurological de cits such as cerebral palsy ( ).Movements of 3-months-old infants were recorded with an electromagnetic tracking system facilitating the analysis of joint angles of the upper and lower limb. A stereotypy score based on dynamic time warping has been developed describing movements which are self-similar in multiple degrees of freedom. For clinical evaluation, this measure was calculated in a group of infants at risk for neurological disorders (n=54) and a control group of typically developing children (n=21) on the basis of spontaneous movements at the age of three months. e stereotypy score was related to outcome at the age of 24 months in terms of (n=10) or no-(n=53). Using the stereotypy score of upper limb movements cases could be identi ed with a sensitivity of 90% and a speci city of 96%. e corresponding score of the leg movements did not allow for valid discrimination of the groups. e presented stereotypy feature is a promising candidate for a marker that may be used as a simple and noninvasive quantitative measure in the prediction of . e method can be adopted for the assessment of infant movement variation in research and clinical applications.

“…It may be determined as the weighted average of positions of the COMs of individual body segments. Characteristics of the movement of the COM over time may be used to assess postural control 9,10 . This pilot study aimed at verifying the potential use of kinematic analysis to characterize the movement of the COM in newborns and determining the difference between groups of preterm and full-term babies.…”

Aims. The objectives of this pilot study were to assess the potential use of 3D videography for analyzing the motion of the body center of mass (COM) in newborns and to determine differences in spontaneous movements between preterm and full-term infants. Methods. The group comprised 10 preterm newborns (gestational age at birth between 26 and 37 weeks; birth weight 800 to 2960 g; gestational age at the time of examination 34 to 39 weeks) and 10 full-term infants (gestational week 38 to 41; birth weight 2810 to 4360 g). To determine the range of motion of the COM, 3D videography was used (2 cameras, 25 Hz). When recording their movements, the infants were in the supine position, calm and awake. The recordings were processed using the APAS software. Selected points on the body were marked to obtain data for calculating the basic parameters of COM trajectories. Results. The range of motion of the COM in both craniocaudal and anteroposterior directions was significantly greater in premature infants (P < 0.05 and P < 0.01, respectively) than in full-term babies. The variability of motion of the COM was significantly greater in the craniocaudal (P < 0.01) and anteroposterior (P < 0.05) directions in preterm babies. This was also valid for the velocity of motion of the COM in the craniocaudal direction (P < 0.05). Conclusions. 3D videography can be used for experimental assessment of motor behavior in preterm infants. Basic kinematic characteristics of the motion of the COM (range, variability, velocity) are greater in preterm infants.
